   #这是注释信息
   sql_query_post 和 sql_query_post_index different?
前者是当Sphinx从数据库中得到数据后,立刻就会运行,而后者只有当索引真正成功建立后才会运行,这个区别还是很重要的。对于真正严格的程序,不应该在sql_query_pre和sql_query_post中更新增量时间,而应该在sql_query_post_index中更新增量时间。还有一个区别是sql_query_post和sql_query_post_index是存在与两个不同的tcp连接中,因为Sphinx从数据库中得到数据后去建索引,将会花费很长时间,所以它会将数据库连接关闭,等到索引建好之后,再去连接数据库,所以sql_query_post_index会在另一个连接中**/
